"Upper Blackrock Spire (commonly referred to as UBRS) is a sprawling 10-man instance locked away within the Blackrock Mountains. Similar to Blackwing Lair (BWL), Blackrock Spire was once one of the strongest strongholds for the Dark Iron Dwarves. However, it has a new owner. The nefarious Nefarian now controls it and is using it as a staging ground to amass his army. The upper level is designed for ten players inside of a raid that are all above level fifty-seven. The upper level contains a wealth of gear that is needed for Molten Core along with the ability to complete quests related to the attunement for Onyxia's Lair and BWL."
